To ail?, whom it may concern:

Be it known that I, JULIUs Berman, a citizen of the United States, residing at Baltimore, -in the State of Maryland, have invented certain 4new and useful Improvements iii-Means for Operating Valves; `and I do hereby declare the following to be a full, clear, "and eXact description ofthe invention, such as will enable others skilled in the lart to which itappertains to make and use the same.

My Ainvention relates to means for operating valves. Y f

LAmong the objects of my invention are 1.-

'To provide a valve'havinga movable part comprising a portion adapted for thefapplication of a special'wren'ch thereto, which portion .is shapedk so that any other wrench applied to said vportion will be disengaged bythe act of turning, thus rendering it impossible to turn the movable portion without the use of a special wrench.

To provide a valve having a movable part comprising a portion for the application of a special wrench thereto, said portion being so shaped that the special 4wrench cannot turn said part wit-hout the cooperation of a locking mechanism secured to said part and any other wrench cannot turn said part etlfen though the locking mechanism is in ace.

p These and other objects of my invention will be setforth in the following specification, reference being had to the accompanying drawings, in which Figure 1 is a plan view of my improved valve, the special wrench therefor being shown in place by dotted lines.

Fig. 2 kis a view of the part shown by full lines in Fig. 1 looking in the direction of the arrow 2 in said figure.

Fig. 3 is a view of the special wrench for use with my improved valve In the drawings:

5 representsl the valve casing which may be made in any approved manner adapted for connection to any desired number of pipes such as 6 which are used to conduct any fluid.

The movable part 7 of the valve may be straight or taper in any approved manner and provided with any number of ports. In the present instance,.it is shown tapered and fitting in a conical hole provided in the casing 5. The part 7 is retained in place in .the casing 5 by the washer 8 and nut 9 threaded upon the endof they part 7.7The end of the part `7 is riveted over the nut 9 as at 10`in order to precludethe loosening of the nut 9 and the turning of the part kI by unauthorized persons. f.

l .A `portionffor the application ofthe special wrench is formed uponthetop ofthe part 7 and said portion consists of the crueiform ribs 11.` The ,ribs 11 have aiiat top 12`again/st which the locl 13 is revolubly secured by the screw 14 which is threaded in the par-t 7. The lock 13 is also ,cruciform -in shapeand has the same contour as the -ribs 11. The ribs-11 are beveled as at15 from the topi 12 to where they meet lthe conical surface of the part 7 in the plane lof the top 16 of the casing'.'

The wrench 17 has a hole 'therethrough bounded 1 by Va cruci'form surface 18. 'The surface 18 is of the same contour as the shape of the ribs 11 and lock 13, but is sufciently larger than either to enable them to readily enter said hole.

l The operation of my improved means for operating valves is as follows By turning the lock 13 so that the arms thereof coincide with the ribs 11, the wrench 16 can be placed upon said ribs in the position shown by dotted lines in Fig. 1. If the arms of the lock 13 are then allowed to remain in coincidence with the ribs 11 when pressure is applied to the wrench 17, the juncture of the beveledl surfaces.` 15 with the sides of the ribs 11 will act as wedges and raise the wrench 17 from engagement with the ribs 11.

The lock 13 is provided in order to prevent raising of the wrench 17 as just described. After the wrench 17. has been placed upon the ribs 11 the lock 13 is to be turned to the position shown in Fig. 1 and in said position it eiiectually prevents the disengagement of the wrench 17 fromA the ribs 11.

`It is evident that no wrench applied to the lock 13 can turn the part 7 because said lock is revolubly mounted thereupon.

It is also obvious that nowrench applied to the ribs 11 excepting the special wrench 17 secured by the lock 13 can turn the part 7 because the beveled surfaces 15 efectually prevent engagement of any wrench with said art. f

p While I haveshown the ribs 11,`lock 13 and surface 18 as cruciform in contour, it

is evident that they may be triform or of any other shape,`provided no surface is presented for the application of an ordinary Wrench thereto. Furthermore, by riveting the part 7 over the nut 9 as at. 10, I insure that considerable power Will be required to turn the part 7, and consequently, inadvertent and unauthorized turning of said part Will be prevented.

Thus it. Will be seen that I provide a simple, cheap and eective means for preventing unauthorized operation of valves which is capable of Wide application, and many changes may be made in my improved valve and the Wrench for operating the same Without departing from the spirit of my invention.

I claim l. A valve comprising a movable part having a portion shaped for the application of a Wrench thereto, surfaces shaped to disengage a wrench from said portion and a lock secured to said part to present disengagement of a Wrench from said portion.

. 2. A valvel comprising a movable part having a portion shaped for the application of a Wrench thereto, surfaces shaped to disengage a wrench from said portion and a lock revolubly mounted on said part to prevent disengagement of a Wrench from said portion.

3. A valve comprising a movable part having a rib for thel application of a Wrench thereto, surfaces on said rib to disengage a Wrench therefrom and a lock secured to said rib to prevent disengagement of a Wrench therefrom.

4;. A valve comprising a movable parthaving a rib for the application of a Wrench thereto, surfaces on said rib to disengage a Wrench therefrom and a lock revolubly mounted upon said rib to prevent disengagement of a Wrench therefrom.

5. A valve comprising a movablev part having a rib for the application of a Wrench thereto, a casing 'for said part comprising a top and surfaces on said rib sloping from said top toward the centre of said rib to disengage a Wrench therefrom.

6. A valve comprisin a movable vpart having a cruciform rib tor the application of a Wrench thereto and surfaces on said rib to disengage a. Wrench therefrom, and a cruciform` lock for said Wrench revolubly mounted on said part.

In testimony vvhereo'f. I affix my signature.
